This is from an interview in the Paris Review in 1955 and describes how he dealt with his literal-minded editor’s questions about this cartoon.

Once I did a drawing for The New Yorker of a naked woman on all fours up on top of a bookcase – a big bookcase. She’s up there near the ceiling, and in the room are her husband and two other women. The husband is saying to one of the women, obviously a guest, “This is the present Mrs. Harris. That’s my first wife up there.” Well, when I did the cartoon originally I meant the naked woman to be at the top of a flight of stairs, but I lost the sense of perspective and instead of getting in the stairs when I drew my line down, there she was stuck up there, naked, on a bookcase.

That cartoon really threw The New Yorker editor, Harold Ross. He approached any humorous piece of writing, or more particularly a drawing, not only grimly but realistically. He called me on the phone and asked if the woman up on the bookcase was supposed to be alive, stuffed, or dead. I said, “I don’t know, but I’ll let you know in a couple of hours.” After a while I called him back and told him I’d just talked to my taxidermist, who said you can’t stuff a woman, that my doctor had told me a dead woman couldn’t support herself on all fours. “So, Ross,” I said, “she must be alive.” “Well then,” he said, “what’s she doing up there naked in the home of her husband’s second wife?” I told him he had me there.
